PCT No. PCT/GB95/02899 Sec. 371 Date May 23, 1997 Sec. 102(e) Date May 23, 1997 PCT Filed Dec. 13, 1995 PCT Pub. No. WO96/19797 PCT Pub. Date Jun. 27, 1996An information processing system (10) receives input data from a keyboard (26), a mouse (28) and spoken data input device (30) in an input data sequence. A microphone (32) converts received speech into electrical signals which are digitized by an analogue to digital converter (100). A digital signal processor (102) converts the digital signals into multi-dimensional vectors which are stored in a temporary input buffer (104). A recognition processor (106) performs a recognition program in order to match the multi-dimensional vectors to speech models. In order that the system (10) may output data in an output data sequence which corresponds to the input data sequence, each data input receives a time stamp. A timing controller (24) ensures that instructions received from either the keyboard or the mouse are output only when those instructions have a time stamp which is earlier than the time stamp of the data most recently processed by the recognition processor. |
